Question

Write an equation of the line in slope intercept form given the following:

1. The line passes the points (2,2) and (4,-2)

2. The line passes the point (3,-2) and a slope of 3

3. A line that has a slope of 1/2 and a y-intercept of 2.

Answer 1

1) (2,2), (4,-2) has slope = 4/-2 = -2, y= -2(x-2)+2 = -2x+6

2) slope = 3, through (3,-2) y= 3x -11

3) slope = 1/2 intercept -2 y =.5x-2
